The Hasty Pudding Club was founded by Nymphus Hatch, a junior at Harvard College, in 1770. The club is named for the traditional American dish that the founding members ate at their first meeting. The Hasty Pudding Club was originally established in Concordia Discors to bring together undergraduates in friendship, conversation, and camaraderie. It is the oldest collegiate social club in America.

The Pudding is currently the only club on campus that is coed and has members from all four years. Membership to the social club is gained through a series of lunches, cocktail parties, and other gatherings, which are referred to as the "punch process". In the past, membership in the Pudding was obligatory to joining waiting clubs and, eventually, final clubs. This tradition is no longer upheld. The Pudding holds its social activities in a clubhouse somewhat near Harvard Square. These include weekly "Member's Nights", dinner and cocktail parties, as well as its elaborate theme parties, such as "Leather and Lace".

The club counts five U.S. Presidents (John Adams, John Quincy Adams, Theodore Roosevelt, Franklin Delano Roosevelt, and John F. Kennedy) among its noteworthy members.

The Hasty Pudding Theatricals, the Radcliffe Pitches, and the Harvard Krokodiloes were founded at the Hasty Pudding Club. All of these groups are part of the Institute of 1770 and share clubhouse space as well as retain various social affiliations with the Pudding; their activities are focused on the performing arts, and they select members through open auditions.
